Photochemical Etching/Milling

Since 1964, we at Etchit have been a leader in the manufacturing of thin precision metal parts as well as providing complete photochemical milling services. Also known as photo etching, photochemical milling, and chemical milling, photochemical machining (PCM) is the process of fabricating sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960’s and can produce highly complex parts with extremely accurate detail. An economical alternative to laser and water jet cutting, stamping, punching, or wire EDM, our PCM capabilities allow us to quickly change the design of a part just by changing the design of the tool. This inexpensive and quick tooling makes our services ideal for prototyping, allows for easy changes in mass production. Our advanced chemical milling machines can maintain dimensional tolerances without creating burrs or sharp edges and can work with many commercially available metals or alloys of any hardness with a thickness from 0.0005″ to 0.040″.

A one-stop shop for precision metal components, we can manufacture parts to exact specifications within a short period of time, whether it calls for a flat blank or something more complex and in a variety of forms or finishes. From one piece prototypes to large volume production runs, all work is done to the highest quality standards. To learn more about our photochemical machining, contact us or see the table below.
